AUTOMATIC SASH HOLDER.

Application iled December 21, 1921. Serial No. 523,950.

.Toy @ZZ (whom t may concern Be it known that I, W ILLIAM B. HUBBARD, a citizen ofthe United States, residing at Smithboro, in the county of Bond and State of lllinois, have invented new and useful Automatic Sash Holder, of which the following is a specification.

This invention relates to window constructions, the primary object of the invention being to provide a. window construction having novel means for holding the sashes thereof in various positions of adjustment,

Anotherobjec-t of the invention is to provide a device of this character including spring means carried bythe sashes andy cooperating within the inner facesof the sash guides to set up a binding action therebetween. y

lilith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing: i

Figure l is an elevational view of window sashes, portions thereof being' broken away 'to illustrate. the invention as applied.

Figure 2 is` anA enlarged sectional view of the. sash holder; and

Figure 3 is a sectional view taken on lin 8 3 of Figure 2.

Referring to the drawing in detail, the reference character 5 designates a window frame. which may be of any desired construction, the saine being formed with suitable guidewajfs invwhich the sash members.

'l move.

ln the present invention, the usual weights and window cords have been supplemented by sash holding devices forming the essence of the invention, each sash holding device embodying a tubular member 8- positioned in a suitable opening formed within the side rail of the sash, one end of the tubular member being formed with beveled surfaces 9 to receive the inclined walls l() of the foot 1l;

The foot ll is formed with a shank l2 adapted to be fitted in one end of the coiled springfl, the coils thereof being of diameters equal to the interior diameter of the tubular member in which the same is posikr tioned. At the opposite end of the tubular member is positioned a head le which is also formed with a shank l5 fitted within the opposite end of the coiled spring 13. Thus it will beissen that due to this construct-ion, the tension of the coiled spring is snilicient to normally urge the foot ll against the inner surfaceof the guideways setting up a binding action suilicient to 'support the weight of a sash and secure the same in its positions of adjustment.

adjacent to thev outer end thereof, a coiled spring positie-ned within the tubular member, afoot having a shank embraced by a portionof the coiled spring, said foot ha ring inclined walls adapted to cooperate with the beveled surface of the associated therewith, to pern i the foot to be moved to a position flush with the outer edge of the tubular member, and said foot adapted to Contact with the supporting bars to support the window sash b v rrictionai contact.

'ln testimonythat l claim the foregoingy as my own, .ll have hereto niixed my? signature in the presence of two witnesses. y
